According to
The Hostapedia by Mark Zilis(2009), "Hosta tibae is
notable for its branched flower scapes and makes a fairly dense
mound of slightly rippled, green foliage...Its scientific name has been
altered a few times over the years. It was known as Hosta chibai in gardens for many years, then briefly
Hosta tibai. Finally the name became Hosta tibae (Schmid1991)..."

This medium size (16 inches high
by around 37 inches wide)
hosta has shiny, green
foliage. It bears purple flowers with yellow anthers on branched scapes in September. The
species originates in
Japan and is similar to
Hosta capitata.

The Hostapedia by
Mark Zilis(2009), states "As a garden specimen, Hosta tibae makes a fairly average mound of green foliage. It
does have a distinctive feature, however, being the only hosta
species with branched scapes."

From the
Field Guide to Hostas by Mark Zilis(2014),
"During a 2012 trip to Japan, I was shown three forms of H. tibae that
differed greatly from the version grown in the United States."
